China’s rise as the world’s leading producer of clean-energy technologies is one of the most contentious issues in global trade. The United States and European Union (EU) in particular regard Beijing’s dominance in solar panels, batteries and electric vehicles (EVs) as a source of industrial vulnerability and strategic dependence.
Yet the overcapacity triggering these concerns is also accelerating the global clean-energy transition by making these technologies cheaper and more widely available as reflected in global trade of clean-tech products that reached an estimated $479 billion in 2025.
Much of this trade has been driven by China's production surplus. In sectors such as EVs, Beijing’s manufacturing has outstripped domestic demand, putting downward pressure on global prices. These cost declines have, in turn, supported faster electrification the world over.
The impact of falling costs is reciprocated in affordability – one of the main constraints on decarbonization. For many emerging and developing economies, limited fiscal space is the major barrier to energy transition. As prices drop, lower-cost imports have expanded their access to clean technologies.
Trade restrictions have a little effect. Rather than curbing China’s clean-energy exports, tariffs and industrial-policy tools introduced by the United States and Europe appear to have redirected a growing share of trade flows toward developing markets.
In many cases, this transition is enabled by Chinese manufacturing capacity. From EVs in Ethiopia to discounted solar panels in Pakistan, China’s industrial scale and overcapacity have lowered costs across many developing economies, contributing to global emissions reductions.
At the same time, volatility in global fossil-fuel markets could add momentum to electrification, prompting import-dependent countries across Africa and Asia-Pacific to diversify their energy mix and increase investment in renewable energy resources.
The International Energy Agency expects energy-sector investment to rise by around 5% to about $3.4 trillion in 2026, despite geopolitical and economic uncertainty. Roughly two-thirds of this capital is projected to go into renewables, nuclear power, grids, storage, low-emission fuels and energy-efficiency technologies.
Looking further ahead, it forecasts total energy investment to reach $3.7 trillion by 2035, with much of the growth concentrated in emerging and developing economies outside China. This indicates that clean energy is seen as a climate imperative as well as a means to bolster economic resilience and supporting development.
As clean-energy investment expands, China's dominance is perceived differently across regions. Advanced economies associate Beijing’s scale with industrial overcapacity; many developing economies view it as an opportunity to gain access to clean technologies at lower costs.
For instance, solar deployment in the EU has grown strongly in recent years, but the bloc still relies heavily on China for solar panels and key upstream inputs.
The same pattern is emerging in EV batteries. The EU efforts to restructure and localize production have eased some overcapacity risks; they have increased reliance on Chinese battery suppliers. As China continues to advance technologically, pressure is building on Brussels to amplify production in strategically important sectors while maintaining affordability.
This creates a policy trade-off for Europe. Greater industrial autonomy would strengthen long-term supply-chain resilience but is likely to raise costs and slow the pace of decarbonization. By contrast, continued reliance on China sustains faster deployment, yet leaves Europe exposed to ongoing dependencies.
The United States faces a similar challenge. Despite tax credits under the Inflation Reduction Act and industrial-policy support for clean-tech production, China accounts for the majority of global clean-tech manufacturing capacity. Washington is scaling deployment in areas such as battery storage, emerging as second to Beijing. Still, as CSIS analysis highlights, expansion in downstream segments does not resolve upstream constraints such as limited domestic reserves and critical mineral processing capacity, limiting the scope of full self-sufficiency.
India follows a different but related trajectory. Its renewable energy installed capacity has expanded quickly. However, the scale gap with China is substantial. This is further evident in deployment where Beijing added 315.1 gigawatt (GW) of solar capacity versus New Delhi's 37 GW.
China’s clean-tech overcapacity has become an essential feature of the global energy transition. While criticized as trade distortion, it has contributed to significant cost reductions in solar, battery and EV technologies, accelerating their adoption across developing, emerging and advanced economies.
Yet, the same concentration that drives lower costs in clean technologies also generates structural vulnerabilities, increasing exposure of importing economies to supply-chain disruption, geopolitical friction, and industrial dependence, as reflected in policy responses from Brussels and Washington.
As demand for clean technologies surges globally, their supply remains highly concentrated in China, with advanced economies seeking to reduce reliance through industrial policy whereas developing and emerging economies prioritizing affordability and deployment.
Beijing’s role in the global energy transition is unlikely to diminish in the near term. For Western policymakers, the challenge is not simply to reduce reliance on Chinese clean technologies, but to strengthen energy security without undermining the pace of electrification.
